Quick-change blade system

A blade mount configured to couple a blade to a rotatable shaft, the blade mount comprising:

• a blade mount base configured to contact at least a portion of the blade;
• a latch assembly disposed proximate to the blade mount base to secure the blade to the blade mount base responsive to operation of the latch assembly, the latch assembly comprising a pivotable clamp, the clamp pivoting relative to the blade mount base;
• and
• at least one magnet receptacle disposed at the blade mount base to receive a corresponding at least one magnet to hold the blade proximate to the blade mount base prior to operation of the latch assembly,
• wherein the blade mount base comprises a set of guide posts and a set of locking posts disposed on opposing sides of a blade reception channel, and wherein the clamp further comprises a locking assembly and a latch cover, the locking assembly enabling the latch cover to be secured to hold the clamp proximate to the blade via engagement of a wire element with the set of locking posts, the wire element being rotatably coupled with the clamp to provide a spring force to pull the latch cover down toward the clamp when the latch cover is rotated such that a substantial portion of the latch cover lies in a plane substantially perpendicular to a plane in which the clamp lies while the wire element engages the set of locking posts.

A lawn care device comprising:

• a rotatable shaft;
• an engine operably coupled to the rotatable shaft;
• a blade configured to turn responsive to rotation of the rotatable shaft;
• and
• a blade mount operably coupling the blade to the rotatable shaft, the blade mount comprising:
• a blade mount base configured to contact at least a portion of the blade;
• a latch assembly disposed proximate to the blade mount base to secure the blade to the blade mount base responsive to operation of the latch assembly, the latch assembly comprising a pivotable clamp, the clamp pivoting relative to the blade mount base;
• and
• at least one magnet receptacle disposed at the blade mount base to receive a corresponding at least one magnet to hold the blade proximate to the blade mount base prior to operation of the latch assembly,
• wherein the blade mount base comprises a set of guide posts and a set of locking posts disposed on opposing sides of a blade reception channel, and wherein the clamp further comprises a locking assembly and a latch cover, the locking assembly enabling the latch cover to be secured to hold the clamp proximate to the blade via engagement of a wire element with the set of locking posts.
